I have a subclass Bar, a 1-dim array which has some methods and some
attributes. One of the attributes is a view of the Bar to permit
Suppose that 'a' is an instance of 'Bar', which has a method 'show' and
a view attribute 'v'.
a ^ 15 returns a Bar instance, with its methods but without the attributes.
I am attempt to change this, Bar has a method __xor__, see below:
def __xor__(self, other):
''' Exclusive or: __xor__(x, y) => x ^ y . '''
<< this loops to the recursion limit
result= ArrayType.__xor__(self, other)
result.v= _n.reshape(result.view(), (n*n, n*n))
Could anyone suggest a workaround please?
